Hummer, Saab, and Porsche all posted tremendously lower sales this June than last. Porsche, worst of all, was down 66%; 902 sales this year compared with over 2,000 last June. Volvo was the only premium automaker competing in the USA to improve on last June’s total, helped no doubt by their larger model range. That being said, numerous luxury brands have larger ranges now and still sold at decreased rates. Check out the graph below for a full rundown of luxury car sales in the USA last month.
